Answer:
Σ(xᵢ-4)², i=1,2,3...
Step-by-step explanation:
Let a score be defined by x
Each score will be xᵢ i.e. x₁, x₂, x₃, x₄... for the first four consecutive scores and so on.
Subtracting 4 from each score = xᵢ-4
Squaring the Resulting Value = (xᵢ-4)²
The sum of the squared numbers = Σ(xᵢ-4)², i=1,2,3...
Σ(xᵢ-4)² is the set of instruction expressed in summation notation.
Answer:
Answer is
Step-by-step explanation:
It is 29 in place of 27 . and Its a geometric series with first term 27 and common ratio
and general formula for given sequence is given by
so plugging the value of a and r ,we get
)^{n-1}[/tex]
B^2 + b = 2
b^2 + b + 1/4 = 2 + 1/4
(b + 1/2)^2 = 9/4
b + 1/2 = (+-) sqrt 9/4
b + 1/2 = (+-) 3/2
b = -1/2 + 3/2 = 2/2 = 1
b = -1/2 - 3/2 = -4/2 = -2
